ALLEN B. BROWVN, OF LOS ANGELES, CALIFORNIA.

VENTILATOR AND DRIP-TRAY.

SPECIFICATION forming part of Letters Patent No. 468,786, dated February 16, 1892.. Application filed July 25, 1889. Serial No. 318,643. (No model.)

To all whom it may concern??- Be it known that I, ALLEN, B. BROWN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Ventilator and Drip lray for Water- Closets and Slop-Hoppers, of which the following is a specification.

The rims of one class of water-closet bowls have heretofore been provided with perforations connected with an escape-pipe for ventilation but the air drawn from the bowls by such ventilators is all taken from that side of the bowl with which the vent communicates immediately; also, the space afforded by the rim of the hopper for such perforations and the channel which connects them with the vent is wholly inadequate to secure proper ventilation, and such bowls have not come into general use.

The object of my invention is to produce a superior ventilation which will remove the local odor of the closet while in use, and also all gases arising from the trap; also, to produce a superior ventilator for this purpose, which can be placed upon any closet or 110pper new manufactured; also, to so construct the same as to form therewith a drip tray or safe to prevent the splashing of water when the closet is flushed. I accomplish these objects by means of the device described herein and illustrated in the accompanying drawings, in which- Figure 1 shows my improved removable ventilator and drip-tray in place upon a Water closetbowl. Fig. 2 is a transverse sectional detail illustrating in part the construction of my invention. Fig. 3 is a vertical mid-section of the upper part of a water-closet bowl in position and provided with my removable ventilator and drip-tray. w m of Fig. 4 indicate the line upon which this section is taken. Fig. 4 is a plan view of my invention with the top removed to expose the chambers A and D.

My invention consists in providing the top of the filth-receiving bowl or hopper of a Water-closet or slop -hopper with an annular chamber connected with a vent and having its interior walls of an inverted-funnel shape to project over the bowl or hopper and provided With openings in such walls to receive the local odor of the closet while in use and the, gases rising from the trap and cause the same to be drawn off through the vent.

It further consists in so constructing the annular chamber and its vent as to allow it to be applied to the bowls and hoppers now manufactured and to serve the purpose of ventilator and drip-tray combined- In the drawings, A is an annular sheet rnetal box adapted to be seated upon the top of the filth-receivin g hopper or bowl V. 13 represents the interior inverted-fu nnel-shaped walls, provided with openings Cand having the projecting horizontal vent chamber or passage D, communicatingwith a ventilating-flue X. The top E of the box is preferably funnel-sliaped to direct the moisture into the central opening Q, and its outer edge is in the plane of the top of the vent-chamber D. The floor I of the box liesin a horizontal plane to fit upon the top of the hopper or bowl, and the floor G of the vent-chamber D slopes upward rear- Wardly from the floor of the annular chamber of the box, so that moisture deposited thereon will be directed into the bowl or hopper through the openings 0. Floor F of the box and floor G of the vent-chamber may be made of one piece of sheet metal, and the downwardly-projecting flange II maybe formed around the central opening Q by pressure. This flange prevents the water from splashing up into the central opening Q. The top E of the annular box and the top I of the ventchamber D may also be formed of a single sheet of metal pressed into shape.

Metallic tongues J may be soldered to the under side of the floor F to be bent upon the ledge K of the hopper to secure the device in place, or other suitable fastenin gs may be provided, if preferred.

The box A is made of various styles and shapes to conform to the various styles and shapes of bowls and hoppers manufactured.

The large passage I am enabled by means of my invention to provide for the exit of the odors and gases gives more complete ventilation than heretofore obtained. In order that made large to give free exit to the air from that side of the bowl, while the other openings 0 C at the sides of the bowl a-nd'O O" at the mouth of the vent-chamberD are made of such size that, while having sufficient capacity to insure complete ventilation, their combined capacity for the passage of air is not sufficient to supply the full current of air passing through the vent-that is to say, the combined capacity of C O C C does not equal the capacity of the vent, so that the draft through the vent will not be whollysupplied through the openings nearest the vent.-

The inverted-funnel shape of the inner walls B of the box A serves to make the ventilation more perfect for the reason that the openings 0 C O" are thus brought over the hopper to catch the local odors while the closet is in use, and also all'the gases that may rise from the trap.

The horizontal vent-chamberDoccupies but little space and is invisible when the closet is set, as it lies immediately beneath the cover W of the closet and passes directly into the wall to enter. flue X.

My improvement can be constructed of porcelain and other suitable material, if desired, and may be made integral with the bowl. WVhen somade, it is well to makethe ventpassage D shorter than shown, in order to prevent breakage. It is obvious that such passage can be made of two sections, if desired, to increase its length and that one section may be made of metal and the other of porcelain. These modifications are, however, suchas will suggest themselves to those skilled in the art, and are therefore not shown in the drawings.

Now, having described my invention, What I claim as new, and desire to secure by Letters Patent, is

The ventilator for water-closet bowls, comprising an annular chamberat the top of the bowl, communicating at one side witha vent and having its interior walls provided on the side opposite the vent with large openings for the passage of air and provided on the other sides with openings 0' 0, having a combined capacity for the passage of air less than the capacity of the vent, whereby a portion of the air passing through the vent is drawn through the openings opposite the vent.
